ExoMol line lists -- L: High-resolution line lists of H $_{3}^{+}$ , H $_{2}$ D $^{+}$ , D $_{2}$ H $^{+}$ and D $_{3}^{+}$

Abstract

New MiZo line lists are presented for the D $_{2}$ H $^{+}$ and D $_{3}^{+}$ isotopologues of H $_{3}^{+}$ . These line lists plus the existing H $_{3}^{+}$ MiZATeP and the Sochi H $_{2}$ D $^{+}$ line lists are updated using empirical energy levels generated using the MARVEL procedure for H $_{3}^{+}$ , H $_{2}$ D $^{+}$ and D $_{2}$ H $^{+}$ , and effective Hamiltonian energies for D $_{3}^{+}$ for which there is significantly less laboratory data available. These updates allow accurate frequencies for far infrared lines for these species to be predicted. Assignments of the energy levels of H $_{3}^{+}$ and D $_{3}^{+}$ are extended using a combination of high accuracy variational calculations and analysis of transition intensities. All line lists are made available via www.exomol.com.
